Welcome to our Ford Truck site.

This just means the oil is getting out as opposed to the coolant getting in.

That usually means hairline crack in either the block or the head.

If the level of the coolant goes up enough,the oil will show in the overflow reservoir.

Have you looked for a Ford Car Related site ?
